# Pre-talk title: An introduction to the SYK model of disordered quantum mechanics

Abstract: Following closely the talks of Kitaev, I will give a more-or-less pedagogical account of the so-called Sachdev-Ye-Kitaev model, a 4-fermi disordered quantum mechanics that began as a study of spin glass dynamics in spin chains and has, over the past two years, evolved into one of the most active current areas of theoretical physics after it was proposed as a simple toy model of quantum gravity. I will describe its many remarkable properties including its large-N, low energy and chaotic limits through the study of its very peculiar Feynman diagram structure.
